The actuator is limited to a maximum opening of 20%. If
“Power Derate 2” is active, it will remain active until the
active DTC goes away and the ignition input to the GCP
(usually the ignition switch) is cycled.
DTC 513: FPP1 higher than IVS limit.
DTC 514: FPP1 lower than IVS limit.
DTC 523: FPP2 higher than IVS limit.
DTC 524: FPP2 lower than IVS limit.
DTC 515: FPP1 higher than FPP2.
DTC 516: FPP1 lower than FPP2.
DTC 353: MegaJector delivery pressure higher than
expected.
DTC 354: MegaJector delivery pressure lower than
expected.
DTC 355: MegaJector communication lost.
DTC 363: MegaJector internal actuator fault
detection.
DTC 364: MegaJector internal circuitry fault
detection.
DTC 365: MegaJector internal communication fault
detection.
DTC 611: COP failure (Internal GCP failure).
DTC 614: RTI 1 loss (internal GCP failure).
DTC 655: RTI 2 loss (internal GCP failure).
DTC 656: RTI 3 loss (internal GCP failure).

failure).
DTC 616: RAM failure (internal GCP failure).
Fault Low Rev Limit
The engine RPM will be limited to a maximum of 1600
RPM. If the “Fault Low Rev Limit” is active, it will remain
active until the active DTC goes away and the ignition
input to the GCP (usually the ignition switch) is cycled.
DTC 511: FPP1 high voltage.
DTC 512: FPP1 low voltage.
DTC 513: FPP1 higher than IVS limit.
DTC 514: FPP1 lower than IVS limit.
DTC 523: FPP2 higher than IVS limit.
DTC 524: FPP2 lower than IVS limit.
DTC 515: FPP1 higher than FPP2.
DTC 516: FPP1 lower than FPP2.
DTC 545: IVS/Brake interlock failure.
Force to Idle
The engine RPM will be limited to a maximum of 800
RPM. If the “Force to Idle” is active, it will remain active
until the active DTC goes away.
DTC 511: FPP1 high voltage.
DTC 512: FPP1 low voltage.
DTC 521: FPP2 high voltage.
DTC 522: FPP2 low voltage.
DTC 513: FPP1 higher than IVS limit.
DTC 514: FPP1 lower than IVS limit.
DTC 523: FPP2 higher than IVS limit.
DTC
524: FPP2 lower than IVS limit.
DTC 515: FPP1 higher than FPP2.
DTC 516: FPP1 lower than FPP2.
Intermittent MIL
Conditions that are only present from time to time are
called intermittents. To resolve intermittents, perform
the following steps:
1. Evaluate the history of DTC’s observed with this
particular engine.
2. Evaluate the symptoms and conditions described by
the customer.
3. Use strategy-based diagnosis, especially where it
relates to the elimination of bad connectors and
wiring.
4. When using a personal computer with Ford
software, data-capturing capabilities are available
that can assist in detecting intermittents. Contact an
EDI customer service representative at (1 800 220
2700) for more information.
Malfunction Indicator Lamp (MIL) DTC
Retrieval Procedure
NOTE: DTC’s can be retrieved from the engine control
module (GCP) by using either the MIL or an IBM
compatible personal computer or hand held Palm Pilot
®
using the optional serial interface available. Refer to
Equipment Setup for information about using a personal
computer to assist with unit diagnosis.
DTC’s can be retrieved by shorting the Self Test Input
(STI) connector to ground. The STI circuit is a white/
purple wire exiting pin 3 of the 42 pin connector. The STI
white/purple wire branches off to terminal “A” of the 4
pin diagnostic connector. If no DTC is stored with key
on/engine off (KOEO), a DTC 123 is flashed, indicating
that all systems are OK.
During key on/engine running (KOER) operation, with
no DTCs stored, the MIL is not illuminated. If during
